BTCC officially introduced today its new bitcoin wallet for iOS and Android, Mobi. It features in-app conversion between over a hundred currencies, silver and gold as well as money transfers by Twitter account and phone number, and an optional Visa debit card.

Accounts are linked to users’ phone numbers and transfers are promised to be instantaneous using Mobi’s private blockchain. From these features, it is obvious that the app was designed with convenience in mind, allowing you to transfer to anyone you know using their phone number or Twitter handle, without the need to remember or send complex cryptocurrency wallet addresses.

The same is true for the optional debit card feature allowing people to spend their money at any shop that accepts Visa and not bitcoin -meaning almost all of them. The card is linked to users’ accounts and automatically deducts expenses from their wallet balance.

Bobby Lee, the CEO of BTCC, gave the keynote lecture at the iFX EXPO ASIA 2017, where he first revealed the app.

“Mobi eliminates friction in money transfer, making money truly global,” said Lee. “With Mobi, you can send any money to anyone anywhere.”

“Mobi will take bitcoin mainstream, with mobile-number accounts, Twitter payments, 100+ currencies, and a Visa debit card,” Lee added. “Mobi is the killer app for bitcoin.”

Mobi is accessible worldwide with support for 15 languages, including English, French, German, Japanese, Korean, Portuguese, Russian, and Spanish.

Despite the use of a private blockchain, the company adds that the app also supports bitcoin transfers on the public bitcoin blockchain.
